The Foraging Ball & Kabob can be a real treat for your bird. It has a slotted durable polycarbonate ball that spins and slides on a stainless steel kabob to stimulate birds mentally and physically. To entice your bird, simply fill the ball with pellets, treats, fruit, veggies, nuts, popcorn or shredded paper, and watch your bird delight in rewarding play. To double the foraging fun, skewer fresh fruits and veggies onto the kabob. The Foraging Buffet Ball & Kabob features a dish underneath to catch spillage.
